and accurately sharpens the cutter links of hand-
held chain saws.
once the sharpener is properly set up for the
chain specifications, the three critical angles of
the cutter link are sharpened with one downward
movement of the spinning grinding wheel. the
next cutter link is quickly and precisely moved into
the correct position for sharpening with the aid of
the adjustable advancement guide. this proce-
dure ensures that all cutter links of the chain are
sharpened to the same specifications.
For your convenience, we post all available man-
uals and manual updates for free on our website
of machine will be reflected in these documents

SECTION 2: POWER SuPPLy
Availability
Circuit Requirements
This machine is prewired to operate on a 110V
power supply circuit that has a verified ground and
meets the following requirements:
Before installing the machine, consider the avail-
ability and proximity of the required power supply
circuit. If an existing circuit does not meet the
requirements for this machine, a new circuit must
be installed. To minimize the risk of electrocu-
tion, fire, or equipment damage, installation work
and electrical wiring must be done by a qualified
electrician in accordance with all applicable codes
Nominal voltage ...............................110v/120v
Cycle..........................................................60 Hz
Phase........................................... Single-Phase
Circuit Size.......................................... 15 Amps
A power supply circuit includes all electrical
equipment between the main breaker box or fuse
panel in your building and the incoming power
connections inside the machine. This circuit must
be safely sized to handle the full-load current that
may be drawn from the machine for an extended
period of time.
Electrocution, fire, or
equipment damage may
occur if machine is not
correctly grounded and
connected to the power
supply.
For your own safety and protection of
property, consult a qualified electrician if
you are unsure about wiring practices or
electrical codes in your area.
full-Load Current Rating
The full-load current rating is the amperage a
machine draws at 100% of the rated output power.
On machines with multiple motors, this is the
amperage drawn by the largest motor or sum of all
motors and electrical devices that might operate
at one time during normal operations.
Note: The circuit requirements listed in this man-
ual apply to a dedicated circuit—where only one
machine will be running at a time. If this machine
will be connected to a shared circuit where mul-
tiple machines will be running at the same time,
consult a qualified electrician to ensure that the
circuit is properly sized for safe operation.
full-Load Current Rating at 110v........ 2 Amps
The full-load current is not the maximum amount
of amps that the machine will draw. If the machine
is overloaded, it will draw additional amps beyond
the full-load rating.
If the machine is overloaded for a sufficient length
of time, damage, overheating, or fire may result—
especially if connected to an undersized circuit.
To reduce the risk of these hazards, avoid over-
loading the machine during operation and make
sure it is connected to a power supply circuit that
meets the requirements in the following section.

Improper connection of the equipment-grounding
wire can result in a risk of electric shock. The
wire with green insulation (with or without yellow
stripes) is the equipment-grounding wire. If repair
or replacement of the power cord or plug is nec-
essary, do not connect the equipment-grounding
wire to a live (current carrying) terminal.
grounding & Plug Requirements
In the event of certain types of malfunctions or
breakdowns, grounding provides a path of least
resistance for electric current—in order to reduce
the risk of electric shock.
This machine is equipped with a power cord that
has an equipment-grounding wire and a ground-
ing plug (similar to the figure below). The plug
must only be inserted into a matching receptacle
(outlet) that is properly installed and grounded in
accordance with all local codes and ordinances.
Check with a qualified electrician or service per-
sonnel if you do not understand these grounding
requirements, or if you are in doubt about whether
the tool is properly grounded. If you ever notice
that a cord or plug is damaged or worn, discon-
nect it from power, and immediately replace it with
a new one.
Serious injury could occur if you connect
the machine to power before completing the
setup process. DO NOT connect to power
until instructed later in this manual.
Extension Cords
We do not recommend using an extension cord
with this machine. If you must use an extension
cord, only use it if absolutely necessary and only
on a temporary basis.
GROUNDED
Extension cords cause voltage drop, which may
damage electrical components and shorten motor
life. Voltage drop increases as the extension cord
size gets longer and the gauge size gets smaller
(higher gauge numbers indicate smaller sizes).
5-15 RECEPTACLE
Grounding Prong
Any extension cord used with this machine must
contain a ground wire, match the required plug
and receptacle, and meet the following require-
5-15 PLUG
Neutral Hot
figure 2. typical 5-15 plug and receptacle.
Minimum gauge Size...........................14 AWg
Maximum Length (Shorter is better).......50 ft.
DO NOT modify the provided plug or use an
adapter if the plug will not fit your receptacle.
Instead, have a qualified electrician install
the proper receptacle on a power supply
circuit that is grounded and meets the
requirements for this machine.

Site Considerations
Weight Load
Physical Environment
makesurethat thesurfaceupon which themachine
is placed will bear the weight of the machine,
additional equipment that may be installed on
the machine, and the heaviest workpiece that will
be used. additionally, consider the weight of the
operator and any dynamic loading that may occur
when operating the machine.
the physical environment where your machine
is operated is important for safe operation and
the longevity of its components. For best results,
operate this machine in a dry environment that is
free from excessive moisture, hazardous chemi-
cals, airborne abrasives, or extreme conditions.
Extreme conditions for this type of machinery are
generally those where the ambient temperature
range exceeds 41°–104°F; the relative humidity
range exceeds 20–95% (non-condensing); or the
environment is subject to vibration, shocks, or
bumps.
Space Allocation
Consider the largest size of workpiece that will
be processed through this machine and provide
enough space around the machine for adequate
operator material handling or the installation of
auxiliary equipment. With permanent installations,
leave enough space around the machine to open
or remove doors/covers as required by the main-
tenance and service described in this manual.
See below for required space allocation.
Electrical Installation
place this machine near an existing power source.
make sure all power cords are protected from
traffic, material handling, moisture, chemicals,
or other hazards. make sure to leave access to
a means of disconnecting the power source or
engaging a lockout/tagout device.
Lighting
Children or untrained people
may be seriously injured by
this machine. Only install in an
access restricted location.

SECTION 4: OPERATIONS
Chain Saw
Terminology
To reduce the risk of
serious injury when using
this machine, read and
understand this entire
manual before beginning
any operations.
refer to the following descriptions and illustrations
to better understand the chain saw terminology
used in this manual.
Chain Component Identification: the cutter
links illustrated in figure 14 do the actual cutting,
while the lower tangs of the drive links keep the
chain riding in the guide bar.
Damage to your eyes, lungs, and hands
could result from using this machine without
proper protective gear. Always wear safety
glasses, a respirator, and leather gloves
when operating this machine.

Chain Pitch: the distance between any three
consecutive rivet centers divided by 2 is known as
the chain pitch (see figure 15).
Top Plate Angle: the profile of the cutter link is
shaped like a number "7", and is comprised of
the top plate and side plate (see figure 17). the
rake that the top plate angles back from the side
plate is called the top plate angle and is generally
25°–35°. this makes a sharp point that begins the
cut.
the chain pitch is the same for all links in the
chain. the smallest chain pitch for handheld chain
1
3
saws is ⁄4", with ⁄8" and 0.325" being the most
popular.

Chain gauge: the chain gauge is the thickness
of the drive link tang (see figure 16) where it fits
into the guide bar groove. the guide bar groove
must match the width of the chain gauge.
Top Plate Cutting Angle: the top plate cutting
angle (see figure 17) is a chisel-like downward
bevel on the underside leading edge of the top
plate that usually is 60°. the combination of this
cutting angle and the top plate angle serves to
remove wood chips from the kerf.
Chain gauges for handheld chain saws range
from 0.050" for smaller chains to 0.122" for larger
ones.
Side Plate Angle: the ground angle of the side
plate leading edge is instrumental in forming the
cutting point between the side and top plates. this
angle is the same as the top plate cutting angle,
which is typically 60° (see figure 18).

gullet Angle: the cutter gullet (see figure 18)
provides a space for the wood chips so they can
be removed by the top plate. on some chains, it
is necessary to have a 10° downward bevel on the
bottom of the gullet that forces the chips into the
path of the top plate for removal.
Clearance Angle: the clearance angle (see
figure 19) is the amount that the top plate angles
down from the leading edge to the rear of the cut-
ter link. this clearance angle allows the cutter link
to pivot up into the wood and then down again
(refer to How the Chain Cuts in the next section
for more information).
Depth gauge: the depth gauge (see figure 19)
is a critical element of the cutter link and is often
overlooked in chain saw sharpening. the height
of the depth gauge must be below the leading
edge of the top plate by the correct amount for
your chain saw. refer to How the Chain Cuts in
the next section and Depth gauge Setting on
Page 28 to better understand the purpose of the
depth gauge.
Left- & Right-Hand Cutters: Chain saws have
left- and right-hand cutter links that together make
the cut. the sharpener must be set up differently
when sharpening left- and right-hand cutters (see
figure 20) because the angles on the cutters are
reversed. it is important to clearly identify the ori-
entation of the cutter before sharpening it.
after sharpening the cutter, always remember to
check, and if necessary, adjust the depth gauge
setting.

the depth gauge setting determines how big of a
bite the cutter takes ("2–3"). it is imperative that
the depth gauge is set below the leading edge
of the top plate by the proper amount so that the
cutter can move into the wood.
How the Chain Cuts
as illustrated in figure 21 below, when the cutting
point at the top of the cutter moves against the
wood ("1"), the front of the cutter pivots up until the
depth gauge meets the wood ("2"), which forces
the cutter to pivot even farther into the wood ("3")
to make the cut.
if the depth gauge is too high or too low, it will
prevent the cutter from pivoting forward and self-
feeding into the wood. refer to Depth gauge
Setting on Page 28 for additional information.
When the rear of the top plate meets the wood
("4"), it forces the cutter to continue pivoting for-
ward and move out of the kerf, producing wood
chips which are carried away by the top plate
angle in the final position ("5") to complete the
cut.
also important is the amount of the clearance
angle. the downward slope of the top plate
enables the cutter to move into the wood ("2")
and then forces it out again ("3–4") to complete
the cut.
always use the chain manufacturer's specifica-
tions for the cutter specifications when sharpen-
ing the chain.
the goal of this rocking motion is to allow the
chain saw to self-feed into the wood and do the
work without requiring the operator to force the
chain into the wood. this makes the job easier
and reduces wear on the saw and chain.

always refer to the chain manufacturer's specifica-
tions when setting up the sharpener.
grinding Wheel
Selection
the grinding wheels supplied with the t23108 are
specific to this sharpener. refer to the specifica-
tions below when purchasing replacements.
grinding wheels that break apart during
operation can send high-speed debris at
the operator or bystanders. ALWAyS visu-
ally inspect the grinding wheel and perform
the ring test (see Wheel Inspection & Ring
Test on the next page for detailed instruc-
tions) before mounting the wheel onto the
sharpener. If there is visual damage or the
wheel does not pass the ring test—DO NOT
use it!

Wheel Inspection &
Ring Test
do not assume that a grinding wheel is in sound
condition just because it is new or looks okay.
often damage can occur in shipping, with age,
or with exposure to moisture, and may not be
visible. inspect every wheel for damage before
installation.
First, do a visual inspection. look for any cracks,
chips, nicks or dents in the surface of the wheel. if
you see any of these, do not use the wheel.
second, do a ring test. this test will give you an
indication of any internal damage that may not be
obvious during a visual inspection. if the wheel
does not pass the ring test, do not use the
wheel.
figure 23. tapping locations for a ring test.
4. an undamaged wheel will emit a clear metal-
lic ring or “ping” sound in each of the four
spots. a damaged wheel will respond with a
dull thud that has no clear tone.
To perform a ring test:
1. make sure the wheel that you test is clean and
dry—otherwise, you may get false results.
—if you determine from the results of the ring
test that the wheel is damaged, do not
usE it!
2. if size permits, balance the wheel with your
finger in the center hole. if this is not possible,
hang the wheel in the air with a piece of cord
or string looped through the bore.

Top Plate Angle
Base mark
it is necessary to have the correct backward top
plate angle from the side plate (see figure 24)
to form the cutting point where the top and side
plates meet, which initiates the cut. this angle
continues the cut and forces wood chips away
from the kerf.

chain holder in relation to the grinding wheel.
3. rotate the chain holder to align the mark on
the chain holder base with the angle mark on
that scale that is right for your chain, then re-
tighten the lock knob.
the chain holder angle scale on the front of the
base (see figure 25) has angle marks to the left
and right of 0°. the angle marks on the right side
of the scale are used when sharpening left-hand
cutters (see Left- & Right-Hand Cutters on
Page 18). Conversely, the angle marks on the left
side of the scale are used when sharpening right-
hand cutters.
Tip: The chain holder is easier to rotate if the
holder tilt is at 0° (see Gullet Angle on Page
24 for detailed instructions).

Sharpening
5. read and understand all the safety instruc-
tions listed in the beginning of this manual
and included with the chain saw owner's
manual.
Operation
in the following sharpening procedure, you adjust
the sharpener settings to grind the correct angles
for the chain, then sharpen each cutter link one
at a time.
6. make sure the sharpener is firmly secured to
the workbench.
7. select and test the grinding wheel that is right
for your chain, as instructed in the Wheel
Inspection & Ring Test procedure on Page
21.
after properly sharpening all of the cutter links,
you need to check, and if necessary, adjust the
depth gauge setting—the distance between the
top plate leading edge and the top of the depth
gauge. Even though the cutter may be properly
sharpened, if the depth gauge setting is not cor-
rect, the chain will not effectively cut the wood.
8. after successful completion of Step 7, install
the grinding wheel onto the sharpener, as
instructed in the Installing grinding Wheel
procedure on Page 14.
the t23108 is not designed to adjust the depth
gauge setting, and it is beyond the scope of this
manual to explain the many methods to perform
this important task (refer to Depth gauge Setting
on Page 28 for additional information).
NOTICE
Always refer to the chain manufacturer's
specifications when setting up the sharp-
ener. However, if this information is not
available, use the chart in Figure 22 on
Page 20 as a general guide.
To sharpen the chain cutters:
1. Clean the chain with a non-flammable clean-
er to remove any oil, dirt, and grime, then use
compressed air to thoroughly dry the chain.
Note: The following instructions begin by
sharpening the right-hand cutters. If you
choose to start with left-hand cutters, keep in
mind the chain holder rotation angle and, if
used, chain holder tilt will be different.
2. Visually inspect the chain and replace any
severely damaged links that could break
apart during sharpening. if replacement is not
possible, use a different chain.
9. rotate the chain holder counterclockwise
(looking down on it) and align it with the cor-
rect rotation angle mark on the scale for the
chain, as instructed in the Top Plate Angle
procedure on Page 22. this setting deter-
mines the top plate angle.
3. make sure all of the cutter top plates will be at
least 1⁄4" in length after the sharpening proce-
dure is completed. this is the recommended
minimum top plate length to avoid the cutter
link from breaking apart during cutting opera-
tion.
10. if required for your chain, set the grinding
wheel tilt to provide the correct gullet angle,
as instructed in the gullet Angle procedure
on Page 24.
—if you suspect that any cutter top plate will
1
be shorter than ⁄4" in length after being
sharpened, replace that link or replace the
chain.

13. position the edge of the advancement guide
behind the cutter to be sharpened, then pull
the chain to the left until the guide catches
and stops the chain (see figure 32).
If the grinding wheel should break apart
during operation, the only thing between
you and the flying debris of the wheel are
the wheel and arbor safety guards. ALWAyS
make sure the wheel and arbor safety guards
are properly secured in place before con-
necting the machine to power!
advancement
guide
11. use the clamp lever (see figure 31) to set
the gap between the clamp plates to match
the chain gauge, which will allow the chain
to easily move along the top of the clamping
bars in the same manner it moves along the
chain saw bar.

Note: Attaining the proper setting for the
advancement guide is a matter of patience
and trial-and-error. This setting is critical to
properly sharpen the cutters, so take the time
to find the correct setting.
Clamp plates
The goal is to position the cutter in relation to
the grinding wheel so that all three angles—
the top plate angle, the top plate cutting
angle, and the gullet angle—will be correctly
sharpened.

14. With the machine still disconnected from
power, lower the grinding wheel into the gul-
let.
12. locate the cutter link with the shortest top
plate length and position the chain so that this
link is under the grinding wheel. this will be
the first link sharpened.
—if the wheel matches the gullet profile and is
against the top and side plates when com-
pletely lowered, the advancement guide is
properly set for now. tighten the knob lock
nut on the adjustment controls behind the
guide to secure the setting.
use chalk or a marker to note the first link to
be sharpened so that you will know when you
are finished with that side of cutters.
Note: If all of the top plates are approximately
the same length, then start with any cutter.
The concern is that all top plates are the
same length when the sharpening operation
is complete to ensure they cut away the same
amount during operation.
—if the wheel hits the top plate or depth
gauge and does not completely lower into
the gullet, or it is not against the top and
side plates, adjust the advancement guide
until it successfully stops the chain in the
proper position. Be sure to secure the set-
ting by tightening the knob lock nut.

15. rotate the clamp lever to the right to firmly
secure the chain between the clamp plates of
the chain holder.
20. using a slow and steady pace, lower the
grinding wheel into the first cutter link until the
depth bolt hits against the depth stop, then
allow the spring-loaded swing arm to raise
the grinding wheel slowly.
16. lower the grinding wheel into the cutter gullet
until it stops, then thread the depth knob bolt
down until it is against the depth stop (see
figure 33).
21. While taking care not to contact the spinning
grinding wheel with your hands or the chain,
rotate the clamp lever to the left enough to
release the chain from the clamp plates.

sharpening.
23. re-tighten the clamp lever and repeat Steps
19–22 until all cutters for that side of the
chain have been sharpened.

figure 33. depth stop and controls.
Important: When adjusting the depth knob
bolt, keep in mind that you want to replace
and sharpen angles that may be worn or
damaged. Do not make the gullet any deeper
than is necessary to accomplish this.
25. release the chain from the clamp plates, turn
it around 180° so that the cutters on the other
side of the chain are ready for sharpening.
26. rotate the chain holder to align with the angle
marks on the other side of the rotation scale,
and, if the chain requires a gullet angle, tilt
the chain holder 10° in the opposite direc-
tion.
Also, taking deep cuts with the grinding wheel
could burn the metal, which will damage
the temper of the steel. Chain cutters that
are heated excessively during sharpening
become brittle and dull quickly.
27. When you are satisfied that the sharpener
settings are correct, repeat Steps 18–23
for the rest of the cutters on that side of the
chain.
It is better to make a few light passes than
one deep one!
17. Back the depth knob bolt away from the depth
stop by a small amount, then thread the knob
lock nut down to secure the setting.
28. Check, and if necessary, adjust the height of
the depth gauges. refer to the next subsec-
tion for more information.
18. adjust the advancement guide so that the
chain moves slightly to the right. this will
remove a small amount from the top and side
plates and provide the sharpened angles.
29. Clean and lubricate the chain per the manu-
facturer's recommendation before re-install-
ing it onto the chain saw.
Note: This critical adjustment is a matter of
trial-and-error and experience.
19. Connect the sharpener to power and wait for
the wheel to come to full speed.

Depth gauge Setting
Clamp Plate
Adjustment
as explained in How the Chain Cuts on Page 19,
the depth gauge of the cutter link forces the cutter
to pivot forward and self-feed into the wood.
if necessary, the pressure of the chain holder
clamp plates can be adjusted to suit your needs.
the depth gauge setting is the difference in height
between the top plate leading edge and the top
of the depth gauge. if this setting (see figure 34)
is too high or too low, the cutter will not properly
pivot and self-feed into the wood.
To adjust the clamp plate pressure:
1. disConnECt maChinE From poWEr!
2. loosen the two cap screws shown in
figure 35. this will allow the inner clamp
plate to be adjusted in the next step.

3. loosen the locking hex nut on the adjustment
bolt, then thread the bolt in to force the inner

it is beyond the scope of this manual to present
the many different methods of maintaining the
proper depth gauge setting. however, it is impor-
tant to state that properly maintaining this setting
is critical to the efficient operation of the chain
saw. no matter how well the chain is sharpened,
if the depth gauge setting is not properly main-
tained, the chain will not be able to efficiently cut
the wood.
4. re-tighten the locking hex nut and the two
outside cap screws.

figure 36. grinding wheel edge profile.
With use, the abrasive surface of the grinding
wheel becomes embedded with material from the
chain, which reduces its effectiveness. in addi-
tion, the side and bottom edge deform and fails
to effectively sharpen the cutter edges. When this
happens, the sharpened surfaces become burned
or discolored, instead of having a clean, silver fin-
ish. additionally, the angles will not be properly
sharpened.
Cleaning
Cleaning the model t23108 is relatively easy.
disconnect the machine from power and wipe
down the surfaces with a damp shop rag, then dry
them with a clean, dry cloth.
use the included wheel dressing block to expose
a new abrasive surface on the wheel and to re-
form the side and edge profiles.
Lubrication
there are not any parts on this sharpener that
require lubrication by the end user.
the bearings of the sharpener motor were lubri-
cated and permanently sealed at the factory and
do not need any further attention unless they
need replacement.
